Implementing a Consistent Colour Scheme

Oct 13, 2025 by wbrum.org 87 views

Overview

In the process of adding smoke tests, it became evident that there is a need for a more rigorous stdout. The current implementation of stdout lacks consistency in spacing, making it difficult to read and understand the output. To address this issue, the first task is to normalise the output, ensuring that every sentence printed has a constant amount of spaces and tabs between characters. The second task is to allow this normalised output to be coloured, making it even more readable and user-friendly.

Requirements

To achieve the goal of normalising output and colour, the following requirements must be met:

Consistent Spacing: Every sentence printed must have a consistent amount of spaces and tabs between characters.
Colour Support: The normalised output must be able to be coloured, making it easier to distinguish between different types of output.
Flexibility: The solution must be flexible enough to accommodate different types of output, including error messages, warnings, and regular output.
Readability: The output must be easy to read and understand, with clear and consistent formatting.

Normalising Output

To normalise the output, we need to ensure that every sentence printed has a consistent amount of spaces and tabs between characters. This can be achieved by using a consistent formatting scheme, such as:

Fixed-width Font: Using a fixed-width font, such as Courier or Monaco, to ensure that every character takes up the same amount of space.
Tab Characters: Using tab characters to separate columns of text, rather than relying on spaces.
Consistent Spacing: Ensuring that every sentence has a consistent amount of spaces between characters, using a consistent spacing scheme.

By implementing these measures, we can ensure that the output is consistent and easy to read.

Colouring Output

To allow the normalised output to be coloured, we need to implement a colour scheme that is easy to read and understand. This can be achieved by using a consistent colour scheme, such as:

Error Messages: Using a bright red colour to indicate error messages.
Warnings: Using a yellow colour to indicate warnings.
Regular Output: Using a standard black colour for regular output.
Highlighting: Using a bright green colour to highlight important information.

By implementing a consistent colour scheme, we can make the output more readable and user-friendly.

Implementation

To implement the normalised output and colour scheme, we can use a combination of programming languages and libraries. For example:

Python: Using the colorama library to implement the colour scheme.
Java: Using the ANSI library to implement the colour scheme.
C++: Using the ncurses library to implement the colour scheme.

By using a combination of programming languages and libraries, we can ensure that the output is consistent and easy to read.

Benefits

The benefits of normalising output and colouring the output are numerous:

Improved Readability: The output is easier to read and understand, with clear and consistent formatting.
Increased Productivity: The output is more user-friendly, making it easier to work with and understand.
Reduced Errors: The output is more consistent, reducing the likelihood of errors and misunderstandings.
Enhanced User Experience: The output is more visually appealing, making it more enjoyable to work with.

Conclusion

In conclusion, normalising output and colouring the output is a crucial step in making the output more readable and user-friendly. By implementing a consistent formatting scheme and colour scheme, we can ensure that the output is easy to read and understand. By using a combination of programming languages and libraries, we can implement the normalised output and colour scheme, and reap the benefits of improved readability, increased productivity, reduced errors, and enhanced user experience.

Future Work

Future work includes:
